Perhaps because of Shava's identity, or perhaps because the Gentle Boiling Man has always been modifying alone, he is eager to share his results with others.
So along the way, even without Angel asking, the Gentle Boiling Man proactively explained the general outline of these magical creature modifications.
The core of the creature modification mastered by the Gentle Boiling Man is the power furnace.
On the black-and-white maid, the power furnace manifests as the heart; on this Bone Leopard, the power furnace is the glowing metal ball within its abdominal skeleton.
Initially, the power furnace appeared to Angel a bit like a power source.
In fact, a power source is the origin of the force that maintains transcendent energy efficiency.
For example, if an alchemy tool suddenly loses its intended effect, the reason is usually due to two situations: either the alchemy tool itself is damaged, or the power source maintaining the effect of the alchemy tool has been depleted.
